- Abstract
Pancreatic islets from A.TH mice were transplanted into the spleen or streptozotocin (SZ)‐diabetic A.TL mice. The two strains of mice are congenic inbred strains, differing only in the I and S subregions of the H‐2 complex. The allogeneic islet grafts decreased blood glucose temporarily, but the islets were rejected after 21 ± 7 days (mean ± SD). The effect of skin presensitization was tested by giving both allogeneic and syngeneic skin grafts to each of a second set of A.TL mice before streptozotocin treatment and islet transplantation. The time course of rejection of the allogeneic islets in animals that received initial skin grafts was decreased to 8 ± 3 days. In both skin‐presensitized and non‐presensitized mice syngeneic islet... (More)
Pancreatic islets from A.TH mice were transplanted into the spleen or streptozotocin (SZ)‐diabetic A.TL mice. The two strains of mice are congenic inbred strains, differing only in the I and S subregions of the H‐2 complex. The allogeneic islet grafts decreased blood glucose temporarily, but the islets were rejected after 21 ± 7 days (mean ± SD). The effect of skin presensitization was tested by giving both allogeneic and syngeneic skin grafts to each of a second set of A.TL mice before streptozotocin treatment and islet transplantation. The time course of rejection of the allogeneic islets in animals that received initial skin grafts was decreased to 8 ± 3 days. In both skin‐presensitized and non‐presensitized mice syngeneic islet grafts were able to restore normoglycaemia, even in animals that had previously rejected an islet allograft. These observations demonstrate that transplantation of pancreatic islet allografts across the I and S subregions of the H‐2 complex is sufficient to induce rejection of the islets. The islet rejection was markedly accelerated by prior sensitization with allogeneic skin grafting. It is suggested that elements in allogeneic skin grafts serve as inducers of cytotoxic T‐cell responses directed against gene products of the I and/or S subregions present on cells in the allogeneic islets.
